Jonh deere ryding lawn mower won't start - John Deere Garden

Try making sure your getting gas to the carb,and to the spark plug if you can choke it and try to start it but fails check the spark plug if its wet with gas then the plug is not firing or your ignition coil is dead also check for debri or foreign matter in the gas lines and filters but if it has set for awhile most of the time the jet become clogged in the carb but most importantly make sure the gas is good and free water dead gas can cause a problem of that nature.hope this helps.
